Question

A beam resting on a simple supports at both ends, which are free to rotate and have no moment resistance. As with any statically determinate structure, the values of all reactions, shears, and moments for a simple beam are independent of its cross-sectional shape and material. What is the characteristic of a simple beam resting on simple supports at both ends?

1) The values of all reactions, shears, and moments for a simple beam are dependent on its cross-sectional shape and material.
2) The values of all reactions, shears, and moments for a simple beam are independent of its cross-sectional shape and material.
3) The values of all reactions, shears, and moments for a simple beam are dependent on the length of the beam.
4) The values of all reactions, shears, and moments for a simple beam are independent of the length of the beam.

Answer 1

The values of all reactions, shears, and moments for a simple beam on simple supports are independent of its cross-sectional shape and material.

Step-by-step explanation:

A simple beam resting on simple supports at both ends is a statically determinate structure. The characteristic of a simple beam on simple supports is that the values of all reactions, shears, and moments are independent of its cross-sectional shape and material. This means that no matter what the beam is made of or what its shape is, the reactions, shears, and moments will remain the same.
